Who split the atom?

Answer 1

It was first split in the Berlin laboratory of Otto Hahn, in 1938. On the evidence of the decisive experiment on December 17, 1938 (the celebrated "radium-barium-mesothorium-fractionation"), Otto Hahn concluded that the uranium nucleus had "burst" into atomic nuclei of medium weight. This was the discovery of nuclear fission. More background info below:

The results of the bombardment of uranium by neutrons had proved interesting and puzzling. First studied by Enrico Fermi and his colleagues in 1934, they were not properly interpreted until several years later.

On January 16, 1939, Niels Bohr of Copenhagen, Denmark, arrived in the United States to spend several months in Princeton, New Jersey, and was particularly anxious to discuss some abstract problems with Albert Einstein. (Four years later Bohr was to escape to Sweden from Nazi-occupied Denmark in a small boat, along with thousands of other Danish Jews, in large scale operation.) Just before Bohr left Denmark, two of his colleagues, Otto Robert Frisch and Lise Meitner (both refugees from Germany), had told him their guess that the absorption of a neutron by a uranium nucleus sometimes caused that nucleus to split into approximately equal parts with the release of enormous quantities of energy, a process that Frisch dubbed "nuclear fission" (fission, as previously used up to this point, was a term which was borrowed from biology, where it was and is used to describe the splitting of one living cell into two). In 1939, Frisch and Meitner submitted their article "Disintegration of uranium by neutrons: a new type of nuclear reaction" to the scientific journal Nature.

The occasion for this hypothesis was the basic and historically most momentous discovery of Otto Hahn and Fritz Strassmann in Germany (published in their first famous article in Naturwissenschaften, January 6, 1939) which proved that an isotope of barium was produced by neutron bombardment of uranium.

The combination of the paper on the experimental and chemistry part of Hahn with the physics paper of Meitner were the foundation of most of the later research on nuclear fission. The claims that the Nobel Prize in Chemistry 1944 should have been given to all participating scientists have been raised on several occasions.

I hope this helps.

Answer 2

They regarded for ones whose nucleii have been much less good, and hence extra easy to cut up. frequently, the heavier the nucleus (the extra protons and neutrons), the fewer good the atom. additionally they needed atoms that are present day in some abundance of course. The heaviest element substantial in nature is uranium. as far as we are in a position to tell or degree, each and every atom of an isotope (like U-238) of uranium (or the different element) is same. So one atom of U-238 is not extra specific than the different.
